I would say this is like a female Dexter, but the Dexter books are more humorous and he is...charming in a weird way. Scarlett, our MC in this book, is out for revenge. She is seen by her peers and her students as stern, cold, and serious. And she is certainly that. But you can't just help but cheer for her (well, I couldn't help but cheer for her) as she brings about justice and death to horrible man-children that have ruined the lives of girls and women through rape or perversion and have gotten away with it. Does that sound satisfying to you? It certainly is for me and so, I recommend this book to you!
